12 Reasons Your Dishwasher Is Beeping – What To Do?

Dishwasher beeping? Dishwashers have sensors that make beeping sounds or display flashing lights to warn the user of a possible issue. If your dishwasher is beeping, you will need to figure out why you hear the beep.

12 Reasons Your Dishwasher Is Beeping - What To Do12 Reasons Your Dishwasher Is Beeping – What To Do

Having your dishwasher not starting properly and beeping is an issue that needs to be fixed. Dishwashers can malfunction as a result from small simple problems, such as a dirty filter, water level issues, soap issues, a wash cycle interruption and more.

The different sounds that dishwashers produce mean different things. If you hear the dishwasher beeping, there are a few things you can check.

Beeping sounds from Dishwasher

If your dishwasher is beeping, you likely need to adjust a component, replace a part, or have the dishwasher reset.

Dishwashers contain electronics with sensors, which may make beeping sounds or display blinking lights to warn the user that an issue has occurred. This is where it may be best to read the dishwasher manual for each unique beeping sound and lights displayed.

Troubleshooting a beeping dishwasher can be difficult, but there are a few potential causes that may help you figure out what needs attention.

1. Try resetting your dishwasher first

To reset your dishwasher if the appliance is beeping, simply try the easiest method first and unplug it from the power outlet. The power cord from the dishwasher is usually located under your kitchen sink. Locate it and unplug the dishwasher for 5 minutes to attempt a reset. Plug the dishwasher back into power after 5 minutes and try running a wash cycle. If the beeping continues, more info is below.

2. Is the dishwasher beeping for 30 seconds?

This is the most common “beeping” in many dishwashers. A beeping dishwasher every 30 seconds usually means that you left the door open. To stop the beeping, simply close the dishwasher door securely and it will start the wash cycle as normal.

3. Dishwasher door opened before finished cycle?

If this happens, it may mean that the dishwasher remembers its last wash cycle status and will not start a new cycle. This may cause the dishwasher to beep since the door was opened during a wash cycle. Since all dishwashers are different, check the user manual on how to restart or reset the dishwasher.

4. Are there too many dishes in the dishwasher?

The dishes in the dishwasher need to be rearranged as too many dishes or a dish blocking a spray arm can cause the beeping sound. Simply rearrange the dishes so nothing is blocking or hitting any moving parts in the dishwasher. Once the dishes are in order, reset the dishwasher and start a new wash cycle.

5. Did you add detergent to the soap tray/dispenser?

A dishwasher can beep if there is not enough soap in the dispenser. Add more soap to the dispenser and restart the wash cycle.

6. Is the dishwasher low on rinse aid?

Some dishwashers will cause a beeping sound when the rinse aid is low or empty. Check the rinse aid area and refill if needed. Restart the dishwasher and start a new wash cycle.

7. Is the start/reset buttons blinking?

Most dishwashers have a signal that indicates they are turned off when the beeping sounds. The dishwasher makes a beeping sound when turning off for around 60 seconds. In this case, you should wait for the dishwasher to reset itself after about 2 minutes. When the beeping and blinking stops, try starting another wash load to see if it will work.

8. Is the water level in the dishwasher too low?

The water level in the bottom of the dishwasher has dropped below an acceptable level and has caused the beeping noise. This may be caused from a faulty float valve, not enough water entering the dishwasher through the water inlet valve, or an issue with hard water clogs. Open the dishwasher and check the components to see if any obvious signs of a fault are visible.

9. Has there been a power surge or power outage?

One potential cause of beeping dishwashers is power surges. To fix this, turn off the dishwasher, press the start/reset button until it shuts off. Then, give it some time and wait 5 minutes before turning the dishwasher on again. If the beeping was caused by a power surge or a power outage, then the dishwasher should function as normal once it has been turned off. Restart a new wash cycle to be sure the dishwasher is not beeping and runs a wash cycle properly.

10. Dishwasher beeps with blinking flashing lights at same time?

This may be a fault in the anti-flood device. This means that the dishwasher has been turned off as it has sensed leaking water or has a fault and thinks the water is leaking into the casing. This issue will cause the dishwasher to beep and the display lights may flash at the same time. This anti-flood device is in the dishwasher to prevent water leakage on your floor. If this happens and water is present, remove the water in the base with a dry towel or similar. If your dishwasher is freestanding, meaning not screwed into place, drain out any water by tilting the dishwasher to remove the water.

11. Does the dishwasher beep 3 times?

If the dishwasher is beeping 3 times or is flashing the display panel lights 3 times this means there’s a leak causing water to accumulate at the bottom of the appliance. You can avoid flooding by turning off the dishwasher water supply. Check the water inlet valve and other components to find out why the dishwasher is leaking.

12. Is the dishwasher filter clogged or dirty?

Check the filter at the bottom of the dishwasher as it may be clogged. See an example of how to check the dishwasher filter here. A dirty or clogged dishwasher filter can also cause the dishwasher to beep. Clean the dishwasher filter and reinstall it, start a new wash cycle and the dishwasher will stop beeping.

  1. Hi! I have a GE GDWF100V55BB. It is beeping every 30 seconds and the control panel doesn’t work. The light is on Auto and Heated Dry but I can’t push any buttons. Whatever happened happened in the middle of a cleaning cycle and I woke up to this. I drained the dishwasher although there was not a lot of water, cleaned filters, and turned off breaker for more than 30 seconds to reboot, and still beeping. Door latches securely. I purchased another dishwasher as I suspect it’s a control board issue of some kind-we also have extremely hard water and there is enough build-up and the dishwasher is old enough so that it’s time to replace.

    However, my new appliance won’t arrive for a week. Any way to disable the beeping before I go mad? Unfortunately, it’s wired to the house, and when I turn at the breaker box it turns off half the kitchen so I have to leave it beeping.

    Help!

      Ann,
      If your old GE GDWF100V55BB dishwasher is still beeping and it is junk and you are going to be ordering a new one, while you wait for the new dishwasher, you can flip the breaker off, even though half your kitchen will go out, and go in and CAREFULLY remove the wiring from the dishwasher to the power wires to the wall. Then put wire nuts on the live wires. Then remove the dishwasher from the kitchen, turn the breaker back on so you have power to the kitchen. Then when you get your new dishwasher it will be a easy to install.

      Just be careful when dealing with wiring, be sure the power is off before attempting this. You can use a multimeter to be sure that the power is off. When you flip the breaker and everything turns off in your kitchen it does not necessarily mean the breaker has turned the power off to the dishwasher. So make sure that the power is truly off before you remove the old dishwasher that is hardwired in the wall. Always think safety when dealing with electricity and try to use a meter to be positive the power is completely off before you rewire things.

      1. It makes 3 beeps every 30 minutes. I ran a normal wash and it worked ok. But again beeps after about 30 minutes (3 beeps)

      2. Allen Vetter - Appliance Repair Assistant

        Rob M,
        GE Dishwasher beeps 3 times every 30 minutes: Try to reset the board first… Press and hold the ‘Cycle Select’ button and the ‘Start’ button simultaneously for five seconds.
        Also try unplugging the dishwasher for 30 minutes.
        You may have a bad pressure switch, excessive rinse aid, or other issues.

  5. Hi, my CDA dishwasher keep bleeping and the start button flashing. I’ve removed the water in the base but still bleeping
    Any suggestions please?

  6. GE Dishwasher model number gdf620hmj2e.
    So randomly the unit would chirp as if the door was open, the lights would come on also.
    Maybe every hour or so.
    After awhile lights would go out.
    This continued for months.
    One day we wanted to run it and would not start, no lights, door closed tight.
    Thought might be door latch.
    Installed new door latch.
    Still no lights.
    There is power to machine.
    Power at control board and door latch.
    Tried resetting by turning off power to unit.
    Its not powered though a GFCI.
    What other troubleshooting can I do to determine the problem.
    Or do you know what the issue is?
    Thank you very much for your time.

      Thomas Tramo,
      So the dishwasher beeps, but now you have an issue with the dishwasher not running at all, no lights, but you have checked it with a multi-meter to see if it is getting power?
      And it is getting power but no lights on the dishwasher come on?
      Have you checked the main breaker that controls power for the dishwasher?
      Is the new door latch wired properly?
      Have you unplugged it for a few hours and tried again?
      You may have a main control board fault…
      Here is the GE dishwasher service manual to further assist you.
